Hello Everyone

This is my entry for "To sail a Technic sea" contest.

SORRY FOR TERRIBLE quality, I'll get better camera tomorrow and will make a new one

Quick overview and some info:

Weight about 4,3 kg

Parts count: more than 4800

Has 2 arms - pneumatic sample arm and heavy duty arm

Uses 4 M motors and 1 XL motor

Uses 3 battery boxes

1 Additional M motor is used to power the heavy duty arm

Has 2 gearboxes - main (the big red one) for operating arms functions

secondary gearbox for operating propellers, tail stabilizer and retracting lights

Has 2 tail (upper and lower) propulsion distributors

and 1 front propulsion distributor.

1 Pilot seat

Length 76cm Width 50 cm Hight 30 cm (without the tail stabilizer)

The whole construction is using a stand, mainly because of the lower gearing system, axles and weight

Functions:

1.The hull has pneumatically opening/closing hatch

2. 2 independent light sources

3. Retracting lights

4. Diving rudders pneumatically controlled from the pilot joystick

5. "Rising" tail stabilizer

6. The "X12" engine.

7. 8 propellers (4 propulsion ,2 vertical, 2 horizontal) driven at the same time from the XL motor (I was trying to make third gearbox for switching between propellers but I ran out of parts and didn't receive new parts yet, I will make this gearbox later)

8. 2 Counter opposite pneumatic pumps running at the same time (when the first pump is recharging the second provides airflow) providing constant airflow

9. Remote controlled switching of gears

10.Remote controlled Left and Right arms

11. 360 degrees rotation of right arm

12. Abduction/adduction of right arm

13. Elevating main boom of right arm

14. Elevating secondary boom of right arm

15. Heavy duty instrument driven by 1 additional M motor (this one is like the Unimog, I'll make lots of different instruments like saws, cutters, drills and other)

16. 360 degrees rotation of the left arm

17. Pneumatically controlled main boom

18. Pneumatically controlled secondary boom

19. Left arm pneumatic grabber. (The left arm can operate between 2 baskets (the lower one sample basket and the left upper one)

20. Abduction/adduction of the left arm.

All Arms functions could be controlled in the adducted, during abducting and adducted positions.

Functions 6,7,8 are driven at the same time from XL motor with additional possibility of powering function #3 or #5

Gearboxes:

1. Main Big red one gearbox is used to power and switch between arms.

2. Secondary tail gearbox is manually controlled and is used to control retraction of the lights and for controlling the "underwater" and "surface" mods of the submarine.

The undone:

I've ordered most of the parts in February and didn't receive the main package with my new shiny hull parts.

The hull supposed to be in different color and shape, but without this package I made what I could.

This creation is my first since "dark ages" I believe I didn't hold Lego parts for more than 10 years.

I hope I will be able to create more.

Oh and I have some photos of building process, some features, prototypes I used in this entry, if anyone is interested - just ask and will post it.

Sorry for mistakes and bad English. :blush:

We have the winner?

That is awesome.

One little complaint though (which is probably not intentional): the inconsistent colors.

Wow! Didn't James Cameron (of "Titanic" fame) use one of these last week to dive to the deepest part of the ocean? :classic:

@ OmiKron

Great MOC and entry for the competition. Loads of functions. I especially like the look of the cockpit, one could think there would be an acrylic glass sphere.

Although one feature doesn't make sense to me at all - the V6 engine one the bottom. Such exploration vessels use batteries or if more advanced fuel cells, since it's hard to get the required air in such depths.

You could have left the engine out and added a small battery box in that place. That would make it appear more realistic.

I'd love to see it shrink wrapped/sealed water tight (if this would be possible be any means) and see it working under water. Note to myself: Suggest watertight PowerFunctions on Cussoo

Anyway - mind blowing Vessel.

Thank you all for the replies. :blush:

I thought about engine problem TinkerBrick before I added it to the submarine.

It is not a v6 - it is X12.

And it is not diesel or oil or petrol engine. I prefer to think that it uses hydrogen and oxygen from surrounding water.

The submarine carries some battery (like the car) to start the synthesis of hydrogen and oxygen from water by electrolysis. Then Hydrogen is used as power source and is burnt (hydrogen + oxygen = combustion) inside the engine providing it's chemical energy. The engine is rotating the generator to make more electric energy which could be stored or used.

The efficiency of this engine type is about 50-80%. Could power the whole submarine for a very long time

Why not, when you are floating in the fuel. :classic:

Good looking engine, but you do realise, that it takes exactly the same amount of energy to electrolyse the water that you can earn from it with burning (The energy you get from burning H and O all goes to electrolyse the water). Taking the energy loss into account, you end up with a less efficient system (with more batteries and gas storing devices) than simply having the batteries power the electric motors directly.

Of course, you could use compressed and stored O and H to power the engine.

Yes, until I use proton exchange membrane energy cells :excited:

Nice looking moc! Lots of nice functions there.

Do you have any pictures of the internal gearing, etc? I think you're at the picture limit in this thread, but if you have a brickshelf or flickr account, please post a link. More pictures would be great!

What does the wire connector hanging out of the yellow arm do? Is that for future attachments?

I love this contest. So many people have uploaded great entries! This is going to be difficult to judge. :thumbup:

I have some pictures of early building process, some prototypes and so on.

The Wire is for controlling the heavy arm's "device". I've got one of the last packages today with extension wires so I'll post photo and video a bit later

Good news Everyone!

I've created brickshelf account and posted some additional photos!

Also made a new video of arms functions (no new camera :cry_sad: , sorry)

Don't know am I allowed to post 2 videos though. If I'm not then I'll delete one of them immediately.

New video is

@ Omikron: Very impressive MOC! Since your Brickshelf folder is not yet "public", nobody except yourself can see your images. It may be several days before the Bricklink moderator makes your folder public. However, you can "deeplink" your images using the procedures here so that people can see them now.

Here are some photos of building progress.

All photos were resized to 800x600 but you can see them in higher resolution in my brickshelf gallery here

I love your model, it's pretty awesome to see such huge models in action and the looks of it are awesome.

Caution! Some of them are pretty big, so they will be under spoiler

This achieves nothing. The image is still loaded regardless. Please just don't post big images. Any topics with oversized images either be invalid or have the images removed, depending on my grumpiness on the day. The rules are there for a reason, don't try to outsmart them.

Don't know am I allowed to post 2 videos though. If I'm not then I'll delete one of them immediately.

You're not. But like most you'll need to make a new topic anyway as this one has too many images. (You can link to this one in the topic though. :wink: )

Thank Yo for clarification! I've edited post and will upload small photos tomorrow.
